I painted above images in Illustrator CS 2. I think that using Illustrator software is more technical and functional. It's not easy if you don't know the basic tool like how to use pen tool or masking or something like that. I didn't know first too, but I do practise as much as I can. The second one has no sketch, it's simple and just need to put effect on polar grid pictures. The girl and the flower is different, I drew the sketch first in my sketch book, and then brought it to Illustrator for painting. Of course, it took time for me to finish. I think more than 3 hours for that. I like the final result. You might see those pictures in Myanmar Graphic Forum Illustrator tutorial section. I posted there at least a little help for beginners.
Thanks for dropping by, Ma Hana. It's strength for me seeing of you people's encouragement in the chat box.
