I think you're great for someone who's been designing for just a week.
I have a couple of tips for ya though. When you're making pictures bigger or smaller, make sure the x and y are at the same percentage so that your people don't go too long or too wide. Also you should try using textures over the pictures and playing around with the properties (I don't know how that works on your program) You should also check out dafont.com for some more fonts.
But apart from that, you're doing really well and you'll do better with more practise =)
