How do I record a loan to the business and advance payment on vendor royalties?

I loaned my business $1,600 through my bank account to cover an advance royalty payment to an author. I am trying to ensure I made all the proper entries. 

Loaning to Company:

Credit $1,600 to Owners Liability -> Loan Payable

Debit $1,600 to Bank Account

Record the Bank Fee:

Debit $100 to Bank Account

Credit $100 to Bank Fee

Advance to Author:

Debit $1,500 to Bank Account

Credit $1,500 to Other Current Assets - > Advance on Royalty Payment

This is where I am confusing myself. How do I record the monthly repayment of the royalty to the company? I created a Vendor Credit on her Vendor Account to apply the monthly bills/payments to her royalty account.

Vendor Credit:

Category: Other Current Assets - > Advance on Royalty Payment $1,500

Vendor Bill: 

Category: Royalty Payment -> $100

Apply Bill to Credit.  

Creat Journal Entry to apply to advance?

Debit $100 to Other Current Assets - > Advance on Royalty Payment

Credit $100 to Bank Account 

Create Journal Entry to Repay Loan?

Credit $1,600 to Owners Liability -> Loan Payable

Debit $1,600 to Bank Account

Am I overthinking things???
