There are many light here. Your light setup don“t help you to reveal the textures of the subject. To reveal textures the light must be in a hard angle setuped to do it. A common setup is a lateral 45 or 90 degrees. But top or down light works well too.
I think more contrast and better focus would help. It kinda looks like it has been brightened or whatnot in post processing, and that has caused some grain to be introduced.
Looks to have been taken with on-board flash, which is absolutely a recipe for wiping out the texture here. All we see is patterns, no sense of the feel of the materials. Looks absolutely flat, so sense of a third (depth) dimension.
nice composition. the exposure could be improved. or possibly the lighting was a little flat, resulting in the blue jeans looking a little washed out instead of a nice rich blue. you've got a nice eye for composition which is harder to get right than the technical stuff.
I think your idea is excellent and the composition is also good.
I don't see focus on any area of your shot. The light is way too harsh causes the colors to wash out. Try to diffuse your light a bit or add some saturation/contrast. Good luck in the challenge.
