Is this you playing after only 4 months??

If so, I am very impressed! You must have played other instruments before?

Whatever you've been doing, it seems to be paying off :) Just imagine where you will be after 8 months, or 8 years!

I think you could practice your bends and vibrato a bit more though. Try to get the bends spot on, and maybe experiment with some wide slow vibrato in a slow ballad song like this one?

Practicing bends with a tuner is a good way of seeing if you're bending flat or sharp.

You could also work on dynamics a bit - play really aggressive once in a while, really pick the notes hard, and then go back to soft playing...

I will say it again - very good job!
