First of all, your astronomy photos are quite literally out of this world. They are all very easy to look at and the ambience that is portrayed by the slightest of lens flare is exquisite, that and the HD helps.

I particularly liked how the background was out of focus, and the background glow just behind the dandelion pod reinforced by the dark atmosphere and a slight blend of other soft, dark colours generally makes this one very good and general purpose. 10/10.
https://www.flickr.com/photos/26934603@N02/14551559205/This picture is quite nice for the fact it is minimalistic. The flash of colour against the blank white background is a simple choice, but at the same time it isn't static. There is dynamic movement going on, and the splash within the glass cup from the ice cube makes this one feel like a frozen moment in time, giving directional sense as well. Can be used for general purpose as well, 10/10. Looks like something the BBC would use at the heading of an alcohol addiction story.

You get a very nice eagle-eye view with everything looking quite neat and orderly, and the different shades of green, brown and grey fading into the distance with the fog is a nice touch, I have to say. 10/10.

Most of the features have been captured just right, and due to the camera, all of the colours flush rightly so against the dull, darkish grey leather background. The lighting is superb and the angle of capture, as well as the moment when it was takin, is will timed and professionally done. 10/10.
https://www.flickr.com/photos/26934603@N02/15360943509/You have captured an immense amount of detail on this one -You can see all the little details of the eye. Colouration, blood vessels, direction, and the glow against the yellow-amber makes it quite beautiful. I personally would make this a 9/10 because more of the eye could do with being captured, but all in all I'll give you a 10/10 anyway because
https://www.flickr.com/photos/26934603@N02/15547563865/Very nicely done. You captured the water drop effect wonderfully. Like the second photo I mentioned, it feels like something frozen in time and it's quite nice if plain. The focus is minutely done so that the focus is on the action itself, and not on the surrounding cup. Not much to say on this one other than a nice stock photo. 10/10.
https://www.flickr.com/photos/26934603@N02/15004729184/A VERY nice image of the Sun without the pesky flares or anything. You can see the sunspots quite well, and gives a very nice ambient feel. Not the best photo I have seen but not at all bad by any standard. The position of the photo feels like it is suspended on nothing in a room of black void, enclosing yet having no form. 9/10: It's a little plain but really that's the only thing.
https://www.flickr.com/photos/26934603@N02/17189141427/This image itself is quite nice. A flash of pink and yellow against a lush background of green is energizing yet easy to look at and soothing as well. A good example of careful focus adjustment and wonderful positioning. 10/10.
https://www.flickr.com/photos/26934603@N02/17209010090/The expression coupled with the focus and monochrome colouring makes this picture a neatley brewed stock. Not much to say on it, but it's very nice with lovely positioning. 10/10.
This is a review of only some of the photos, my favorates from them all. I hope this helps you in your future creative efforts, and I personally support your work. Very nice all in all.
