They're not my Frodo and Sam either, but I actually like that. It's too easy to get stuck in one particular image of them, especially with the films. (That's one thing that made me uneasy about the movies coming out - the idea of the characters getting frozen like that.) So I welcome different versions of them, as long as the artist is skilled.

Here is a drawing that Giancola did of Frodo:



I really like this drawing, and it's very close to how Tolkien described Frodo. He doesn't look like a young boy, and his hair is short, as described in the book. I also love the pensive look on his face.
