My first initial sketch:

I had a problem to fit letter F into O and C into U because there are so many space between them and if I can't figure out, its look so empty and I only got this idea. As for S, I lowered it down to it snug between tail of U ( I hope its acceptable).

I also make a little bit space for upper tail of C to U to differentiate between letter or else it will look like O, I think its looks good like that even it can be closer.

After refining, concave affect and all, I come up with this.

PS : I don't need distort effect because my hand already made it and they hate me.
