First of all English is not my first language but I hope you understand anyway and dont get me wrong

There are a lot of great ideas in your playing but Im feeling that you have to play with a little more confidence. What Im trying to say is "Play like you mean it" Still play your riffs as you do now, just getting even more into it. I know itīs easy to say but Im just saying what I was thinking when I was listening to your music.
Great tone by the way, sometimes I could hear a hint of overdrive, is that your amp or are you using a Tubescreamer or something similar?
Maybe you could try to change the tone maybe halfway in (more overdrive) and play a little more agressive. In that way you get more variation and it can even sound like there are two guitarist.
For me the tone it self have a BIG influence on my playing. I will say, I nearly automaticly get into a more agressive playing with more overdrive or distortion. You will also get more sustain that way, which brings me to my last point. I can see you are writing about your bends and vibrato. Try to give it even more vibrato so we really can hear it and feel it. Your bends are most of the time great.
Your feeling for the music are great and you follow the music very well.
I hope all make sense, and remember itīs all ment positive

Cheers
