Hey hey!! @bryanlz8764
I'm glad to know that you like the drawing!

Wow what a coincidence! I was recently looking for a tablet (I don't have the money yet, but I'm doing some research first ahahah) and I saw about it, I thought the features were decent! how is it?! I would like to know how it behaves, since the seller says that it is good, but it is not the same as having it in your hands!

As for the other! I keep learning every time, I can only advise you something that has worked for me in approximately 5 years.
See, practice, be a little sponge (absorb everything) and try to emulate how others do or how things look, after that little by little you go your own way..

Draw constantly, I used to do it practically every day and it was with colors, but well, I admit that I have stopped doing it so often, that is not good because you become slow!

Something that I really like is asking the person who is next to me at that moment what they think about what I am doing... that has helped me many times to fix something that perhaps I saw was right, because I am simply doing it and the truth is not that I think my works are magnificent (in fact I've never thought so hahah) but maybe I think it's fine the way I'm doing it and no, maybe there's something weird... So those comments they are valuable because they are the ones that help you improve.

See things from a very different perspective, we must try to be very self-critical with ourselves, see those mistakes that are there and sometimes we do not want to see... no conformism, always look for more!

What is magnificent now and that also helped me a lot is to watch videos, on Youtube you can find everything from how to make a nail to how to make a Concept Art! There are also videos that are very important about colors, values, anatomy, color theory and many other things that will help you get better and better.

What little I know I have learned by watching, I never went to an art school... If you like to draw, that passion will lead you to experience many incredible things!

As for the working tool, I use PS to draw with an old Wacom bamboo.

What tool do you use?
Sorry for my late response, very busy days!
