Super impressive!
Definitely stick to this medium of those lovely pencils on paper guy, it looks stunning!
You really seen to understand shading, definition and shadows and it comes through so strongly that your style is far better suited to this than digital, as not only do you capture those wonderful details that make this piece 100x more superior to those works you previously have made digitally, in digital you lose all those glorious aspects that make this far and above the best thing you have ever produced but you also seem to be a natural with this.
You should consider playing around, further practicing, having fun and experimenting with different materials such as charcoal on art paper to really show off that great burgeoning shading technique of yours by highlighting those wonderful shadows in monochromatic silvery greys on a nice grade of paper, some decent art pastels to really get those colors to pop and heck even try watercolors, I think you will create some truly stunning art on canvas in time.

Take your time, make mistakes and have fun!
You’re a natural!

Will requests be open at some point?

Gonna use those spells to further impress Twilight
