Hi Willem,
For a first 54mm it looks quite attractive.
Since you ask for feedback let me try to give you a few constructive comments.
Overall, the white and reds very much determine the looks of this figure and these colours could use more contrast and variation in tone.
For example, the white is largely plain white, with one intermediate, coldish grey midtone, and only a minor extreme shadow. It would look more interesting to start with a warmer off-white mix and only use plain white on a few selected highlights and more intermediate tones. And very important are the extreme shadows and (very dark, but thin) outlining of the borders with other colours. Particularly such outlining will improve the look of a figure quite a lot I find. Look at Fernando Ruiz's online course here at the forum for an excellent reference (better than I can do it).
For the red leather try to make a graduation from darker tones at the bottom to lighter ones going up in the vertical direction. And again make sure the belts etc. are thinly but clearly outlined by a very dark colour.
The face is very well done, but also here I suggest you try a bit more contrast, adding a few selected deep shadows and high highlights. The overall tone is very good however.
The metals are very well done. Looks like you polished the white metal and used washes. A fail-safe and good-looking method that just looks great.
I hope this is of any help.
Have fun and I'm looking forward to your second 54mm...!
Cheers,
Adrian
