i would suggest not using marker and/or colouring anything in, use a pencil so you can fix things when you recognize a mistake, for example, you might realize that your A is hidden behind your J when your rocking a sketch, and that way you can erase it and play around with where you think it would sit best. have patience and really force yourself to buckle down and keep it simple, you're on the right track. most beginners, if not all, try to jump hurdles that they arent prepared for, and naturally, it sets them back. you'll look back and be thankful you learned the basics of strong letter structure, so you dont have to be one of those cats who hide behind those fancy extensions and know inside you cant rock a dope simple... hope this helps, lets see what ya got.
