Nice job.  Yes, I'd double+  the blue..  But i don't see yellow at all, so I'd dump that Warm Sepia, get some Quin Gold (while you still can) and really pound that in.  Yellow is important and very forgiving (i.e., you can overdo it and still not ruin the pic). 

Great first attempt.

OK, I tried a tricolor gum today with the intent of getting true color. Using 1:1 gum/dichromate ratios and sun exposures of 3 minutes and 30-60 minute development, I ended up with this:
My guess is that I'm not putting enough pigment in my mixes...especially the blue pigment.
I used Prussian Blue, Warm Sepia, and Anthraquinoid Red...all Daniel Smith watercolors.
