1. Expect Criticism
2. You've had so many topics in this board, when you need to stop making topics, and just practice your modeling. If you would just practice instead of shooting out stuffty models on the forums, I can almost guarantee you'd be better pretty quick.
3. There are two types of add-on makers/ modelers. The ones who make them for fame, and the ones who make them for the community. You seem to be making them for fame, because when people keep saying they are bad, you say
You can't force me not to model so gtfo will ya
You need to listen to criticism, and if (intelligent) people keep coming here and saying your models suck, it's your models, not them.
Now, here's is my criticism. When you add a cylinder, put the faces down to 8, because when you have 32, like your binoculars and scope, it looks like stuff and is very high-poly.
