Of course, not trying to be rude, but 1,000 - 1,300 for a basic icon like that is pretty absurd. I’d pay about 50 for that if I didn’t know how to make GFX. There are some really good tutorials out there, though. But pretty good for beginning.

HIGHLY Suggest adding more commissions, it shows you are capable of expanding your commissions to other genres and unrelated topics towards a particular theme. Otherwise as someone has stated before me, Id improve on the trees and Mountain, and I personally dont believe that text fits the sort of theme your going for/ someone else was thinking of ( I could be mistaken! )
