Let's start again

So here I am.

In just two months, (awhile) Winter will turn to (come to a close to make room for the) Spring (, just two months left) and we will be able to see the magnificence (magnificent) of nature with its (his) marvellous (marvelous) colours.
To tell (say) the truth, I can't wait to be catapulted into a new season and enjoy (make) new experiences, new encounters.
The most amazing thing, that some may not find (for someone could be not) so interesting, is that finally by that time I will be studying in Cambridge. (and) I am looking forward to viewing (having a look to) the city, the different types of architecture and to being surrounded (sourranded) by a fresh English sound for my ears.
Throughout this time, I will definitely have to improve my communication skills (to make myself clear) and in the meantime to pick up the language to the best of my ability. (as much as I can.)
At times, just changing (change) your life-time habits for a while can instil fresh (bring you a new) inspiration (for your life, new) and motivation(s)  , capabilities that previously lay (were) hidden within. (in you.)

You have some good descriptive phrases. I have suggested a few alternatives you might use. The only major thing with the construction was your sentence commencing 'The most amazing.....'. Personally, I thought you had too much information in one sentence and it was a little long, so maybe better to separate into two sentences. Otherwise very good. This will be a great opportunity for you. Good luck!
