I will critique your work. It seems as though you are skilled in photoshop but lack artistic skill. Similar to me. I can cut and past and change colors and put text to your same ability. Yes it would make a good t-shirt design most of the time but if you're getting those images off google, or other websites, you could get in trouble. If this is what you enjoy doing then I won't tell you to stop. I will tell you though, if you want to get good attention from the people that know whats going on here, you should try making everything from scratch and focus more on the artistic side of it, and not the "hey look I can put cool things together in photoshop" side of it. Thats just my opinion; I've been using photoshop forever but just recently started freehand drawing in photoshop. All my stuff pretty much sucks so far but I feel better knowing that everything I've done is mine.
