Hate to say it, but this is not one of your most inspired outfits.
Starting from the top, the hat is not well rendered. First off, the fore and aft bills are too narrow; they should meet up with the ear flaps. The ear flaps themselves are too wide; they should only be wide enough to fully cover the ears.
Here's a page with several good pictures of Deerstalker caps being worn.
Even more than the magnifying glass, Sherlock was known for his
Baskerville pipe, and there isn't one in this drawing.
Next, the typical Sherlock Holmes outerwear is the
double layered Inverness cape, which this figure doesn't have at all.
Then there is no variation of color or pattern between the ribbon bows and bodysuit, or the suit and skirt. This is atypical of anything you've done before. The tights also shouldn't be the same pattern as the upper body, although there is at least a minor color variation on them. It'd be better if they weren't patterned at all.
Fortunately, most of it's easy fixes, and I think you did a great job on the hounds-tooth patterning.
