That is really incredible. 100k stitches in... Wow. Not much less than I've done in my lifetime so far.
It is a remarkable looking image, and HUGE! I love the wolf portraits and to combine that with a motorbike. Hmm, can't get much better than that (I took a bike from Vancouver to Fairbanks and then to Toronto in an amazing trip after leaving college and only learnt to drive a car at age 25). Only thing the image is missing to make it perfect is a cat, but can't have everything
.
As for the more powerful 'orangey' colour, I think I can give an explanation, if nothing else.
HaED use a piece of software called 'Pattern Maker' to do the conversions. This seems to rely on the same public domain thread colour definitions as 'PCStitch', 'Ryijy Stitch Designer' and my own 'BlendThreads' software (and probably others). As far as I can trace, the thread definition file seems to originate as an unofficial (and therefore non-contractual) release by DMC. In the thread colour definitions B5200 White has value 255/255/255 for the red/green/blue components, and Black has 0/0/0. Now, in reality, that is impossible as all white colours absorb some light, and all blacks reflect some. In a photo I've taken of these threads I've had B5200 white come as 232/232/232 and 310 black as 7/7/7. In order to cover the possible range of colours, I think someone at DMC tweaked the figures to stretch the range so that the digital image range of 0-255 for each colour component was covered. An un-intended consequence of doing so was that they made the average colour definition lighter than, and less saturated than, the real threads (though for a few darker threads the colour definition will be darker than and more saturated than the real threads).
So, what you find is the resulting stitched image tends to be about 10% darker and be a richer, more saturated version of the digital image unless you do a bit of photo processing prior to converting the digital image (by making it approx 10% lighter). On the basis of seeing a number of their stitched images, I do not think HaED do much image processing prior to their conversions, so the pictures will tend to look a bit darker and more saturated than the digital image that was converted. (The 'Pattern Maker' software seems to have issues of loss of texture in dark areas too, but that is not going to be a noticeable issue in this image.)
Having realised that these problems exist, and wanting to cater for extreme faithfulness to the original image, on my own software I have included an optional modified thread definition file that makes the definitions darker to reduce the effect noted above. However, I hope sometime soon to create my own DMC definition from scratch based on a photo of a DMC floss card. I wish PM, PCStitch etc would invest the time in doing it for themselves too.
Hope this explains the colour deviation, even if it can't do anything to alter it.

I'm using 20ct easy count white Aida, here is what I have done so far
