Rebeccak: This REALLY helps! Thanks a lot! I will try it! 
Gisaiagami: I’m an awful begginer, so don’t pay me so much attention. All I can say to you is that I was really afraid of painting in grayscale, too. But I found that’s a matter of practise and, in fact, you could find it easier than painting in color. Grayscale is the first step, color is the second.
Did you made your drawings on paper or with a tablet? I’m asking you this because it’s easier for me to work on paper. I just can’t draw on the tablet, I’m terrible doing that.
I love to see your works here. Keep on going! And don’t forget that you have a great guidance, and it’s name is Rebeccak. 
Regards!
Bless
