If I may offer some constructive criticizm, you should make sure that skin tone is uniform. Right know it looks unnatural, with head being rather dark and with face being much more brighter.
No offense, but I find their one looks more natural then your one. It may be your gama setting or something, but in your version, the doctor appears to be yellowish. It certainly doesn't look natural for a human. Both skins are very nice though.
