That doesn't seem like something to get mad about. Perhaps it's just me giving off a wrong impression that I would be sensitive to criticism, but I would even go far enough to say that I am the last guy I know who would be sensitive to criticism.
The shine could be too much, but that all goes to what style is intended, and there are many styles which are possible here. But, if you are saying that it is too much as in it takes away from the quality of the colours then I would look back and try and figure out something different.
I'm looking back now and will try out some other things.
