With the first one my worry would be that the I is a bit too challenging. On first glance the capital I looks like a lowercase l which will only lead to confusion.
On both, I enjoy the injection of colour that the squiggle adds but am not sure what the squiggle itself is there for? Maybe lose the squiggle, add that colour to the crown and lift it away from the top of the I?
With the second one, the first m and the uppercase C run into each other. The tittle on the i looks uncomfortable, as though its there by mistake.
