This is a nice illustration on its own, but in my opinion the galleons are not the proper ship model for the Iron Fleet. The entire concept of the ironborn draws them much closer to the vikings than to the 16th-18th century seafarers and the general atmosphere of Song of Fire and Ice is high medieval, not baroque.
Please keep doing more drawings! Cause this is great! Not a request/commission but a suggestion, I'd love to see you draw Yae Sakura from Honkai Impact 3rd in your art style. Look it's up to you that's all.
