A Job Well Done
If this is your first submission, I look forward to seeing more flashes you produce.
Just a few points:
Could you put a little more detail into the houses next time? Even with the cartoony feel, they seemed to much like 'cardboard-cutouts'.
The rain in the background was good, but maybe change the sky a little? It seems a bit too grayish.
Last point and I'll shut up. While I have no idea why the guy before me wants THIEVES to have 'cool fighting styles', how about heightening the tension while Dagger creeps around? Suspense is just as good as fighting in the correct circumstances.
