This is Donald Glass, aa character I created entirely in Blender based on an image I found on Pinterest.
You could use Donald as a a guide to practice character sculpting in Blender.
The character was created majorly in the Sculpt Mode of Blender. The head was sculpted seperately from the neck before being joined and retopologized.
The materials are quite basic but produce a good enough result.
The eyebrows, mustache and beard along with the tie were modeled normally in Blender.
You can leave a feedback. You could also ask any question you have regarding the creation of the model or regarding Blender in general.
Don't hesitate to contact me if you need more models like this. You could also check out some other models I have puploaded here on CGTrader including some free models.
Thanks.
