May 2018 Sketch Tier Sketches 13-16 (Patreon)

Here's 13-16 of the May sketches!  There's one more batch of 3 to come.  If you're a Sketch Tier, Sketch+Secret Gallery Tier ($20), or Custom Card Tier patron, let me know your choice over the weekend.  Otherwise I'll pick one at random.

The sketches are as follows:

13. South Sphere engineer design

14. First sketch of Samsid's bathroom (I did this a previous month but then redid it and never sent out the original)

15. Yackley with flowers in his beard

16. Jordana
