Um, what do you mean with CG arts? O.o; if it's about CG gallery, you can find a free basic CG gallery codes by leon on lemmasoft!
Oh and did you get your steam key? If nkt, drop your email here and I'll send you one today ^.^
Aaah! Sorry I got confused there x'D
Then you're doing great! I had a headache when I was configuring the CG gallery for the first time so I just assumed x'D but you're doing great! There's no rush for the CGs, I think you should take your time looking for pose references via real life photos or from a comic book and start from there :'3 for the background, you can cheat a little by blurring it *cough* or use your ingame background and set it to accomodate the CG! (You know, zoom it in and use transform to adjust the angle, lightning, etc...) I often use this techinque to save time ><
