WOW
I don't think many people here on NG will truyl appreciate how difficult it would be to make this. I've done a few still life with pencil, graphite pencil, molding erasure, etc but this is completely different. First of all, like the person below me stated, you were very brave and actually very good with your attempt to make glass. I think it is extremely difficult to capture the right reflections and shadows with any form of class that has curves to it. I like the contrast between the cloth which is rather rough to the preciseness off the glass bottle.
There are errors but I consider still life to be so much more difficult than most of the forms of art you see on NG. I think the review below me pointed out practically everything that could be considered wrong with your art. Yet again, I think you have done a wonderful job with the colors like you did and especially with your still life style. Making still life period is hard but you've also added considerable color. Very very well done.
