Congrats on your first LO and welcome to SBB. The link you posted was to your gallery. If you want to post a direct link to the large view of you LO here are the steps.
1. After you upload your image you will be returned to your gallery page. Click on the thumbnail of your LO to get the full view.
2. Copy that link address and paste in your post just like you did with you gallery address.
If you would like the link to have the name of your LO here are the steps.
1. In your thread post type the name of your LO
2. Highlight it and then click on the little blue ball with the chainlink at the top of where you are typing your message.
3. A box will popup and you can enter the link address to your address. Make sure you highlight what pops up in the URL box if it isn't already highlighted otherwise the address you paste in will have two http:/ things and the link won't work. Hope that makes sense. Your message post will look a bit like extra jibberish but it will clean up when you post it.
Here is an example of what I'm talking about:
