You need more copyspace for the pencils. the un-isolated image and small copyspace (blank area for text etc) limits the usefulness. Second picture: altough the background is out of focus, it is still too complicated and background and objects colors are harmonic, which makes hard to distinguish the object. They can still sell :) but you need some improvement and it's very normal. You are very new :) welcome to DT :)
well, what about then saying, there's a bit work to do on the lightning and think from the view of the buyer, does this sell?? the biggest challenge in life is to be honest but also encouraging - tough, I know, and I probably fail myself heaps of times ;)
Don't share that opinion at all- I reckon the picture with the girl holding the pencils has the potential to sell well and considering that they are the 2nd and 3rd accepted files I think they are really great - would like to look up your 2nd and 3rd pic "Costasz"!
