Simp1 is a strange picture. Looks like she's dragging herself from an accident or somthing. Its hard to make out, but it doesnt look like she's enjoying it.
Your hair style for Maggie is a good way to draw it I find. Its more natural and blends in with the rest of the family, unlike some designs I've seen.
Simp2, very... upsetting? Perhaps, but still good. You've clearly got talent using both pencil, and tablet for computer art. The perspective, is off but not by much. The guide box and lines are obviously helping.
Simp3. Hmm, she needs work on her arms, and possibly her eyes. The face seems off proportion.. and I'm not sure why...
Its a good try though, Marge is a very hard character to draw.
Simp4.... Hehee!! *laughs uncontrollably*

I love it

A great idea, and well designed!
Simp5, heh! Thats a good idea too! Clearly its just drawn for a laugh, but the idea is still very good. I hope we'll see a nice clean version one day

Simp6, awwww.... cute ^^ She's drawn well, in a very nice style. She is the angel.
Simp7, hard to make out but, the only nit pick I see is that her head is a lot larger than I would call 'normal'. However, this could be because she is very young.
Whew... got through them eventualy

Some really nice sketch's and good ideas. I hope to see more
