You don't need to be good at photoshopping... I still don't use it and I have quite good pics...
And for stats, see my thread for the Beast (link in my signature) and see those statistics ;)
Indeed, I could have gotten a pic from internet, but then I would pick a picture of a 'Cyromancer' class or whatever from another game just like you did with your beast idea. Then the pics just don't look like the troops in Clash of Clans, which make your idea look like some rip-off (not offending you) from another game. I checked out your thread (you are not allowed to advertise your thread btw XD) and all stats I saw I didn't had was the upgrade cost and time, which isn't really important (SC won't use your exact stats anyways). So, if you could specify what stats I exactly need to add I would be honored :).
