I'm not so sure what style you are going for, but i really like the sketchy and thick lineart look, altho the eyes look a bit wonky, i think the reason why is because they are different sizes, but you can fix that by using a sketch guide and using shapes, also join the YTUBA(YouTube University for Broke Artists) there are lots of pro artists with a wide range of artstyles you can learn from, and also, i think the direction of the characters eyes is perfect, it looks like he is looking at me, but remember, practice makes perfect, keep on doing what you love @neonical
having the eyes look a certain direction is always hard :') However you can make some practice sketches where you experiment with eyes on faces while looking a certain way ^^
