I never understand why gfx designers always see something to criticise in the competitors... If you guys think the quality is too bad or the prices are too high, just let this shop die with the lack of buyers.
Grudge, I highly reccomend you to make some top-notch sigs for free before trying to make some paid works. I'm saying this because I started a shop more than two months ago and until now I only got 5 or 6 serious requests. After opening a free gfx store, I got two paid requests in less than one week. Also, the people from here won't buy something from you if you don't show them all your potential, specially with the big concurrency we have here in Sythe. But it's only a suggestion, you don't have to follow everyone's oppinions if you don't feel like it. Anyway, Best of luck with your business.
