My first tuck planche attempt - paraletes

After a month of training planche leans on the floor and on the paraletes I decided to try to hold tuck planche on paraletes. I finally cold lift my feet of the floor and hold it for few seconds. But I was not satisfied with my form and I felt slight pain in my left forearm.

Here is my attempt, a lot of hard work and such small progress. It was very frustrating.
