First off, welcome. I have to say i definitely like your moc. From the break up of the walls (not only with color but shape) to the stained glass windows(?) this moc shows a lot of character. Keep up the good work!
Cool looking tower! You put a lot of nice detail into it, I especially like your staircase, the four 1x1 plates over the door and your color scheme on the corners of the tower. Beautiful first MOC.
Wow, This is really good! The building and details have a nice classic feel and you didn't make it overly fancy. Simple but interesting: The perfect Combo(but I don't think there are and castles in the Caribbean )
I always liked the Dragon Masters theme and felt that they did not have enough "cred" among AFOLs. That said, your MOC keeps the color scheme and "spirit" of the original sets quite nicely. Is there an inside? If not, then I recommend creating one as a future improvement. Nice work.
