This is my first attempt to a Sci-Fi type of building and even tho it's small, I kinda tried to pack some details in there.
If you have any suggestions to improve/change feel free to tell me. Tho try to make it informative and not just "YOU sUXXXX". Also, link some inspirational pics if you have some.
I like it, I would say that you should change the orange to a more contrasting color such as a nice blue but it is your choice, I generally build Medieval as I have gotten quite used to that with my time with FyreUK and several other build teams, so I don't really know how to talk about Modern as its not what I'm used to, but from what I can see I do like it! I would say also try and add some scenery such as modern trees maybe try some random blocks which aren't allways used so for tree's maybe some blossom tree's or some slime blocks and some other cool blocks to make it look more new and unique. Hope this helps!
