Yes, I agree. Rimfrost is already in use, but not 'Rimfrost
Software'. Secondly, it's my team partner who chose the name, because it was not yet taken as a company name. So, he registered the name 'Rimfrost Software' and payed for it. It's only registered in his country for the moment, as it would cost much more to register it worldwide.
Quote: "Nobody does animated logos except beginners. Animated title is used for video animation like trailer or game intro."
Not according to
THIS article. Plenty of professional logo designers use some form of animation.
Quote: "Slightly modified font Neuropol Regular ($), red stroke 1px, some bevel and emboss, some "texture" and ripple effects."
You're right about the (free) font, but not really on the other parts.
Quote: "Do you really want your logo "to say" that you are very beginner? No offence, just keep working! This time no luck."
Well, I'm not an expert on logo design, but I don't think it's that bad, I hope?

I'm always trying to improve my work, so...who knows...
Thanks for the suggestions, though!
