Hello CCD!
I was watching your pics a long time... First to say, I love your kind of drawing styl. One of my favorite. It is because of the faces, they look kind of cute and different at the same time (especially the short mouth and the smaller overbite).
The only thing you can work on are your Computer-Colorings. Try to make smoother lines and less flat shadings on body, clothings and enviroment. The good thing is your use of colored lines - thats IMO very difficult and you do it well.
The first Lisa-picture in this thread seems very good to me, also with the interisting lyric. You like to add inspirating poems to yoz pictures, too? Me, too.
It makes the message in the pictur more clearly (often of cause).
Okay, you may have done better folding-shadings on the dress, and that pink doesn´t tast that much (*munch munch*
) but it´s okay anyway.
The second picture seems a bit complicated to rank. I guess it is okay. 5 points of 10 possible points. But, hey, I don´t like to rank. It´s a good try. The sky looks a bit simple and Lisa from the back is strange to look at. Keep on drawing anyway.
Ah, and you will, how I can see. Lisa in happy Donut-Land? *smile* Whoa, I love how Marge looks to her sweet Homie. Very good expression - just the hair is a bit toooo high. Try to color it, will you?
Almost forgot that Wing-picture: Looks nice to me, especially that exaggerated Wings. Pew, saw too much Wings-Lisas on this message board and I cant say anything more thant: Nice.
Oh, the picture with those letters I love, it is selfe-expressionistic art. Shows your dedication to Lisa, your little obsession, mh? Love that very much, cause I remember the times I drew pictures with Lisa over and over agian. And additional it´s not easy to draw paper with stuff. I like that note "Please privacy..."
The next one is a very good one. Reminds me of the old MarcoBerzacolacism back in ´03. Those where the times. All well, first the critic: The saxofon needs more details. I know this, I am playing it and there are some buttons and holes lost. Don´t know how to explain that in English, sorry.
Adult Lisa is very sweet. The body is very Anime-like. Maybe the eye looks a bit odd, but it doesn´t matter I guess (just repair that sax, pleeease!). I love that bows. Keep on drawing and stay tuned.
I found my favorite in this thread: Little Marge. How cute you have done her. And again that kind of drawing styl of the mouth and overbite - love it. The only thing you could do better is the coloring. Also the Lisa picture needs that. I like what you do with her hair.
Now try a huge picture that will take you hours of hours to work on. You can do that and I love crowded, filled and stuffed pictures.
So much from my side. Hope you like my statement.
Excuse my writing skills, I hardly wrote English the last month.
Bye!
last I have not had time to draw…. but of all ways… they are here…. 
..... nevertheless to draw is an art by own right? it is not necessary to be expert… single a pencil, a paper is needed…. 
….
..... really one is based on real facts… was a drawing that was on the verge of erasing 
)… perhaps MAggie...
