Moved some coin from paper wallet to Mycellium, is the balance still mine?

The btc amounts below are made up, just for clarity.  I am getting conflicting information online about this (mostly that I'm screwed but it doesn't seem like it?)
I have 10 btc in a paper wallet - simple public key and private key, in a safe.
I opened Mycellium, and clicked spend from cold storage, and entered my paper key private key and put 2.5 btc in my Mycellium wallet.  I then spent 1btc of that from my Mycellium wallet.
I checked the public address balance of the paper wallet on blockchain.info and it was 7.5 btc, as expected.  Can I still access this paper wallet's funds with my same private key in my safe? Is it still secure, and considered cold? It's been a month or two since the Mycellium transfer, and it's still showing the balance on the public address for the paper wallet but I read some info online (about change addresses) that made me think it was either not accessible anymore or not secure.
Thank you! Super worried.

1) You can still access the funds using your paper wallet just as before.

2) However, as you exposed your private key to an online device, it's effectively not in cold storage anymore, thus not as secure as it used to be. I'm not sure whether Mycelium stores the private key you import from cold storage though, if Mycelium deletes the key after sending the transaction the situation might be not quite as bad.

In the end I'd recommend moving your funds to a new paper wallet (or a hardware wallet, for that matter), assuming that you don't feel comfortable with keeping the balance in a hot wallet.
