Good job on making the service for free, it's a way to learn, although to be honest if you've been doing this for 3 years I would think you would be doing something different.
By the way, you're saving your work as jpg, why in the hell is that? start saving them as png, and remember that layer styles like drop shadows or bevel and emboss/outer glow etc isn't everything to it, sometimes less looks better.
Not trying to hate, I started the same way on this very same forum![]()
