Hmm, no offense but can you bull.... anymore, i could have done that on paint, you didn't sell that... I do web designs myself, and some of the best out there struggle to sell. You've made simple rectangles with the marquee tool, you've filled them with a colour, then you've but the transparency down, you've added a simple gradient overlay to the blue... I'd say the choice of colour for the text is the best thing about the piece.. I mean did you try to bevel and emboss that blue bar??...
Don't take it personal bro, but when your gunna talk .... about selling it for $75, then im gunna tell you why you didn't and couldn't sell that for $5.
