Speaking of fighting in the aikido style, I could tell from my first class that it will be hard to adjust from boxing/kickboxing style striking and defense to aikido. I'll get the hang of it eventually though.
You might talk to your instructor about that... most aikidoka are pretty terrible at strikes. It might be better for them to imitate you than for you to imitate them... Certainly the Zombie Fist of Doom that you see in many dojos is pretty unrealistic.
