Everything's great. The composition and all, maybe AA those jaggies underneath the teeth a little bit, but that's it. Fantastic work from you yet once again!
Pretty good so far. There are some jaggies (rough edges) on the bigger planet. Maybe you can add a galaxy-type thing in the background to fill in the gap between the planets. Don't be afraid to experiment.
No, I don't have a tut for that. I saved all my files on separate disks to keep my computer clean, but I think I might have the file saved somewhere. If you like, I can send it to you via your e-mail. Just shoot me a PM if you're interested.
Nice work. It seems like there's something missing on the left, but it still looks great as is. Maybe I'm used to making things look so busy all the time. Who knows.
