I got Paint tool SAI on my other computer and just went straight ahead with it.
Did a few tests
First test:

Second test

Third test

CNC

Maybe play around more with the dillution and persistence settings to get more of a "paintbrush" feel? Idk just something I would do c: Cool little tests though broski! ^-^

The blue lightning in the third test looks awkward, i guess but besides that these are amazing

they were good ...but if you want to have a nice work...try photoshop!

not bad, i would say Sai is actually a pretty good software for art too, im not sure if photoshop is so much better than Sai but for me if you're just gonna paint, i said go with Sai, but yeah maybe i just dont know photoshop that much, or maybe it is better, but anyways this is good enough for practice, and idk, you have always been good, LOL XD

but you know it depends on the user style!
i mean someone like to work with photoshop and someone like to work with sai!
some people are better with sai....and some people are better with photoshop!

SO see this because it mades with photoshop!

I think those are the best pictures in sai I have ever seen

you obviously havn't seen Tenma's or Tatel's drawings
