Beautiful! I love the blue trim, it's a bit change from the gold. Good shading! I seems to hold it self to a higher standard, showing indeed a motherly like approach. There are of course ways of making her more "motherly" But Jack clearly beat me to the punch there. I just realized how the lines on the outside really add to the image. The facial features are a new touch! And the fact their there give a bit more character to this "Architect". The arms are a bit off putting, compared to the otherwise well proportioned figures shown in previous images. The shading is a bit wonky in a couple places, but yet again, Jack beat me to it!

Awesome work on this. I really love the figure and the colors used. The shading on the mother contrasts nicely with the bolder solid tones of the background and that gold; and man, the use of the metallic gold there is awesome and really adds a ton of punch to the drawing, I imagine it looks even better in person.
The stripes in the background do a great job at accentuating the figure and the bolder red keeps the largely empty space to the left from feeling empty and wasted while also pushing attention further to the right (to the figure) while the gold sliver to the left keeps us from going off of the page, excellent work on that.
While I personally really like the proportions you have going on here with the elongated arms, and such I think it would better suit the theme of "Mother" if you were to accentuate more traditionally motherly parts, hips and bust are generally what I can think of, though some props would bring it out more, but that could definitely clash with the composition of the piece so it's a hard point to argue, and the piece overall does fine without - just something to think about in the future.
Also last point on this is one of the pitfalls of doing traditional work, the image here brings the drawing down. The lighting could be stronger and more uniform, you may have to move some lamps around to get the desired lighting, you may want to do some light tampering with the brightness, values and contrast in a basic photo editor to get it to look closer to how it would under ideal lighting conditions. Also cropping the image a bit to cut out the excess where we go off the page will greatly help the focus. Those issues don't destroy this drawing, but if they are fixed fairly easily since they don't deal with the drawing itself.
Hope this helps in some capacity. Awesome work, I definitely look forward to more.
