Sounds like you've started off well! Agree with PRSPlaya - Line6 presets are pretty synthetic. What you have there is pretty good!

Have you downloaded the latest Gearbox software? Then go on-line and there are some good tones to be found in the 'tonelocker' and in the library, and also some pretty good BT's to play along with. Some of the users have come up with some interesting sounds...
