No, everything looks in proportion. I know the Torsk has hand wheels that are very large and others that are small. Really, all looks great! In fact, the two hand wheels you are talking about are very large on the Torsk. These wheels are about 200 pounds each. So, no, you hand wheel looks fine.
My poor computer drawing skills. I have circled this wheel on the Torsk. It is large like yours. In fact, I think you are dead on with your wheel size.
