Fellow artist here, observing your process, good use of construction shapes it's the most intuitive way to draw. Also perspective Gesture drawing show you grasp the principles of art as well as the elements of art.
This is so relaxing to watch and the sketches and colors are neat and detailed. Its so hard to draw Sonic characters (at least for me) but you drew them Amazing!
This is pretty cool! It's honestly amazing how dynamic your sketches and drawings are, not to mention clean. I hope I will be able to draw like you one day. Other than this, good job and excellent work!🐢
