First of all, welcome to the forums and congrats on your new property! I'm still a rookie, but I can give you my 2 cents of what I've learned so far from the wonderful people on this site.
The plan is to have a small island in the middle
Just remember that islands have 2 major negatives. One, they take away from the surface area and holding capacity of your pond, and two, depending on how big you make your island, you will need a way to access it for mowing, maintenance, etc.
a max depth of around 35 feet
By most people's standards, this would be considered a
very deep pond. To achieve those depths in a ~2 acre pond, you'll also have to have some pretty steep banks. Depths like that won't be used very much, if at all, especially if you get a thermocline, which will create a "dead" zone of water with little to no oxygen. I think the consensus around here is to stay at around 8-12' for a max depth, maybe 15', to utilize as much of the pond as possible, and to avoid a thermocline. Bass, in particular, won't be in 35 feet of water very often, regardless.
