Let's make a bookmark for my friend

Hi everyone.
Today, I am really excited to post in this community for the first time. I am happy that I am going to show my work to these community members and I am going to be the family member of this community as I heard that this community is really amazing and it is so diverse so I have come in this community to share all of my hard work that I am doing for myself for my family members and for my customers. I am going to share a bookmark which is for my friend. My friend loves sunflower is so this bookmark is totally inspired by sunflower. As you can see that I have made it two sunflowers on both sides. But before I start the procedure I just want to say that if I make any mistake in today's post or if there is anything wrong you all can tell me the comment box as I am reading all of the comment and I will try my level best to reduce the mistake which I have done today.
Let's get started.

At first , I cut the brussel board into the size of a bookmark, which is a usually rectangular shape. I asked from my sister weather I have got it correctly or not and she said that you had made some mistakes in that it is not noticeable but she said it is so you all tell me whether it is or not. After cutting days, I have outline the borders with the black pen.

After the outlining, I have drawn semi circles on the sides.

After drawing The Circles, I have drawn the petals on both of the sides with the pencil of not equal shape just to be realistic.

After the sunflowers I have drawn the leaves on the sides.

After this I have outline them with the black pen.

Then after that i have coloured the middle part with the brown color.

For the petals outline I have used the orange colour first.

After that I have a coloured inside with the yellow colour marker.

For giving even the more realistic look I have used orange colour pen for the petals to give like a hair look inside the battle you know like we are making to give the realistic look. Thats wht i did there too.
